anastomosis

(ə-năs′tə-mō′sĭs)
n. pl. anastomo·ses (-sēz)
1. The connection of separate parts of a branching system to form a network, as of leaf veins, blood vessels, or a river and its branches.
2. Medicine The surgical connection of separate or severed tubular hollow organs to form a continuous channel, as between two parts of the intestine.

a·nas′to·mot′ic (-mŏt′ĭk) adj.

anastomosis

[ənas′tōmō′sis] pl. anastomoses
Etymology: Gk, anastomoien, to provide a mouth
1 a connection between two vessels.
2 a surgical joining of two ducts, blood vessels, or bowel segments to allow flow from one to the other. A vascular anastomosis may be performed to bypass an aneurysm or a vascular or arterial occlusion. With the patient under anesthesia, a section of the greater saphenous vein or a synthetic prosthesis is grafted to the prepared vessels. Postoperative nursing care includes preventing tissue injury and wound infection. Lack of blood flow may allow the graft to close. Pulses distal to the anastomosis are evaluated frequently. Capillary refilling time and the color and temperature of the skin are checked. Prophylactic antibiotic therapy may be started within hours. Urinary output is monitored. Kinds of anastomoses are end-to-end anastomosis,end-to-side anastomosis,side-to-side anastomosis. See also bypass. anastomose, v., anastomotic, adj.

anastomosis

Anatomy
An interconnecting aggregation of blood vessels or nerves that form a network plexus.
 
Surgery
(1) Any opening between two normally separate spaces, lumina or organs, regardless of the manner—surgical, traumatic or pathological—in which the opening was created.
(2) The surgical connection between two tubular structures (e.g., end-to-end anastomosis of the colon or rectum) after a cancerous segment has been excised, or end-to-side anastomosis of a saphenous vein during a CABG.

Anastomosis

Surgical re-connection of the ends of the bowel after removal of a portion of the bowel.

anastomosis

communication between two blood vessels or other tubular structures

anastomosis 

A natural communication between two blood vessels or other tubular structures. Example: the long posterior ciliary artery divides into two branches as it enters the posterior part of the ciliary muscle and at its anterior end these branches anastomose with each other and with the anterior ciliary arteries to form the major arterial circle of the iris. See major arterial circle of the iris.
